Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541218, here are decompositions:

17 + 541201 = 541218
37 + 541181 = 541218
89 + 541129 = 541218
131 + 541087 = 541218
157 + 541061 = 541218
191 + 541027 = 541218
211 + 541007 = 541218
229 + 540989 = 541218

Showing the first eight; more decompositions exist.
